This is five-fold proportion The first ratio gives solution namely We will write general proportion a:b= c:d= e:f = g:h= i:j = k According to this the first ratio gives coefficient k When we divide 24/2 =12 our coefficient k=12
In the second ratio we will multiply 3 with 12 and get 36. In the third ratio we will multiplu 5.5 with 12 and get 66. In the fourth we will divide 108 with 12 and get 9. In the fifth we will multiply 15 with 12 and get 180.
Finally the ratio is 24:2=36:3=66:5.5=108:9=180:15
$310 dollars because after it res and decreased it gained $.10 and 100 x 3 is 300 so thats before you calculate how much it rose so .10 x 100 is 10 so add that to 300 and you get 310
